Rock wool products use basalt, dolomite, etc. as the main raw materials. After being melted at a high temperature above 1450 ℃, they are centrifuged at a high speed by a four-shaft centrifuge to form fibers. At the same time, a certain amount of binder, dustproof oil, and water repellent is sprayed into the cotton. The machine collects, passes through the pendulum method, adds the three-dimensional method to spread the cotton, and then solidifies and cuts to form rock wool products of different specifications and uses.
